Halfway Between 80 and 638

When you ask "What number is halfway between 80 and 638?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=80 and Y=638.

Halfway Between Line

To find the number halfway between 80 and 638, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 638 into our formula, we get:

(80 + 638)/2 = 359

Thus, the number halfway between 80 and 638 is 359.

To check that our answer is correct, we subtract 80 from 359 and subtract 359 from 638 and compare the two numbers:

359 - 80 = 279
638 - 359 = 279

As you can see, the halfway number is 279 higher than 80 and 279 lower than 638. Therefore, our halfway between answer of 359 above is correct.
